Calliphora hortona. 



Musca hortona, Walker, Cat. Dipt, in Brit. Mus., p. 894 

 (1849). Pollenia aureonotata, Macquart, Dipt. Exot., 

 Supp. 5, p. 135 (1854). 



Head and antennae piceous, a reddish or fulvous patch at 

 the base of the antennas. Eyes hairy. Palpi and proboscis 

 piceous. Thorax with a pyriform yellowish fulvous spot on 

 each side in front. Abdomen brilliant violet-blue. Wings 

 with a fulvous spot at the base. Length, 9-10 mm. 



Hab. Wellington and Christchurch (F. W. H.) ; on the 

 sea-beach. 



In this species the antenme are short, not reaching the 

 epistome, the third joint being only about twice the length of 

 the second. Also, the hairs on the arista are not so long as 

 usual in the genus. I have a specimen in which they are 

 developed only on the upper side, as in Idia. Also, the fourth 

 longitudinal vein is very slightly arched after the bend. 



Calliphora icela. 



Musca icela, Walker, Cat. Dipt, in Brit. Mus., p. 897 (1849). 

 Call, aureopunctata, Macquart, Dipt. Exot., Supp. 5, p. 130 

 (1854). 



Vertex blackish-brown, cheeks yellowish-white in the 

 male, passing into tawny on lower face and abdomen. In 

 the female there is on each upper cheek, from the upper 

 facial ridge to the eyes, a reddish-brown patch, margined 

 above and below with yellowish-white, and the lower face 

 is brown. Antennas piceous, the second joint reddish. The 

 eyes are bare, and only approximate in the male. The palpi 

 orange or fulvous. The thorax has an oval fulvous or orange 

 spot on each side in front. Abdomen brilliant blue, some- 

 times with faint - green reflections. Wings with a fulvous 

 spot at the base. Length, 7-9 mm. 



Hab. Throughout New Zealand.

 large orange or fulvous spot between the eyes and the upper 

 facial ridges. The eyes are bare. Third joint of the antennae
